BACKGROUND OF THE INVENTION

G Protein Coupled Receptors

G Protein coupled receptors share a common structural motif. All these receptors have seven sequences of between 22 to 24 hydrophobic amino acids that form seven alpha helices, each of which spans the membrane. The transmembrane helices are joined by strands of amino acids having a larger loop between the fourth and fifth transmembrane helix on the extracellular side of the membrane. Another larger loop, composed primarily of hydrophilic amino acids, joins transmembrane helices five and six on the intracellular side of the membrane. The carboxy terminus of the receptor lies intracellularly with the amino terminus in the extracellular space. It is thought that the loop joining helices five and six, as well as, the carboxy terminus, interact with the G protein. Currently, Gq, Gs, Gi and Go are G proteins that have been identified.

Under physiological conditions, G protein coupled receptors exist in the cell membrane in equilibrium between two different states or conformations: an “inactive” state and an “active” state. A receptor in an inactive state is unable to link to the intracellular transduction pathway to produce a biological response. Changing the receptor conformation to the active state allows linkage to the transduction pathway and produces a biological response.

A receptor may be stabilized in an active state by an endogenous ligand or an exogenous agonist ligand. Recent discoveries such as, including but not exclusively limited to, modifications to the amino acid sequence of the receptor provide means other than ligands to stabilize the active state conformation. These means effectively stabilize the receptor in an active state by simulating the effect of a ligand binding to the receptor. Stabilization by such ligand-independent means is termed “constitutive receptor activation.”

Serotonin Receptors

Receptors for serotonin (5-hydroxytryptamine, 5-HT) are an important class of G protein coupled receptors. Serotonin is thought to play a role in processes related to learning and memory, sleep, thermoregulation, mood, motor activity, pain, sexual and aggressive behaviors, appetite, neurodegenerative regulation, and biological rhythms. Not surprisingly, serotonin is linked to pathophysiological conditions such as anxiety, depression, obsessive compulsive disorders, schizophrenia, suicide, autism, migraine, emesis, alcoholism, and neurodegenerative disorders. With respect to anti-psychotic treatment approaches focused on the serotonin receptors, these types of therapeutics can generally be divided into two classes, the “typical” and the “atypical.” Both have anti-psychotic effects, but the typicals also include concomitant motor-related side effects (extra pyramidal syndromes, e.g., lip-smacking, tongue darting, locomotor movement, etc). Such side effects are thought to be associated with the compounds interacting with other receptors, such as the human dopamine D₂ receptor in the nigro-striatal pathway. Therefore, an atypical treatment is preferred. Haloperidol is considered a typical anti-psychotic, and clozapine is considered an atypical anti-psychotic.

Serotonin receptors are divided into seven subfamilies, referred to as 5-HT₁ through 5-HT₇, inclusive. These subfamilies are further divided into subtypes. For example, the 5-HT₂ subfamily is divided into three receptor subtypes: 5-HT_(2A), 5-HT_(2B), and 5-HT_(2C). The human 5-HT_(2C) receptor was first isolated and cloned in 1987, and the human 5-HT_(2A) receptor was first isolated and cloned in 1990. These two receptors are thought to be the site of action of hallucinogenic drugs. Additionally, antagonists to the 5-HT_(2A) and 5-T_(2C) receptors are believed to be useful in treating depression, anxiety, psychosis, and eating disorders.

U.S. Pat. No. 4,985,352 describes the isolation, characterization, and expression of a functional cDNA clone encoding the entire human 5-HT_(1C) receptor (now known as the 5-HT_(2C) receptor). U.S. Pat. Nos. 5,661,024 and 6,541,209 describe the isolation, characterization, and expression of a functional cDNA clone encoding the entire human 5-HT_(2A) receptor.

Mutations of the endogenous forms of the rat 5-HT_(2A) and rat 5-HT_(2C) receptors have been reported to lead to constitutive activation of these receptors (5-HT_(2A): Casey, C. et al. (1996) Society for Neuroscience Abstracts, 22:699.10, hereinafter “Casey”; 5-HT_(2C): Herrick-Davis, K., and Teitler, M. (1996) Society for Neuroscience Abstracts, 22:699.18, hereinafter “Herrick-Davis 1”; and Herrick-Davis, K. et al. (1997) J. Neurochemistry 69(3): 1138, hereinafter “Herrick-Davis-2”). Casey describes a mutation of the cysteine residue at position 322 of the rat 5-HT_(2A) receptor to lysine (C322K), glutamine (C322Q), and arginine (C322R) which reportedly led to constitutive activation. Herrick-Davis 1 and Herrick-Davis 2 describe mutations of the serine residue at position 312 of the rat 5-HT_(2C) receptor to phenylalanine (S312F) and lysine (S312K), which reportedly led to constitutive activation.

DEFINITIONS

For clarity and consistency, the following definitions will be used throughout this patent document.

The term “agonists” shall mean moieties that interact and activate the receptor, such as the 5-HT_(2A) receptor, and initiates a physiological or pharmacological response characteristic of that receptor. For example, when moieties activate the intracellular response upon binding to the receptor, or enhance GTP binding to membranes.

The term “antagonist” is intended to mean moieties that competitively bind to the receptor at the same site as agonists (for example, the endogenous ligand), but which do not activate the intracellular response initiated by the active form of the receptor, and can thereby inhibit the intracellular responses by agonists or partial agonists. Antagonists do not diminish the baseline intracellular response in the absence of an agonist or partial agonist.

The term “contact or contacting” is intended to mean bringing the indicated moieties together, whether in an in vitro system or an in vivo system. Thus, “contacting” a 5HT_(2A) receptor with a compound of the invention includes the administration of a compound of the present invention to an individual, preferably a human, having a 5HT_(2A) receptor, as well as, for example, introducing a compound of the invention into a sample containing a cellular or more purified preparation containing a 5HT_(2A) receptor.

The term “mono-valent-metabolically-labile group” as used herein refers to any group that, following administration of a compound containing the group to an individual, is converted in vivo to a compound of Formula (Ia) wherein R^(4b) is H. The conversion of the “first metabolically-liable group” can be by metabolic and/or chemical processes and can occur in one step or through a series of two or more steps. Representative examples of a “mono-valent-metabolically-labile group” include, but are not limited to, —C(═O)O—R^(4c) (thus, together with the nitrogen forms a carbamate), —C(═O)—R^(4c) (together with the nitrogen forms an amide), and the like, wherein R^(4c) is C₁₋₁₈ alkyl, aryl, arylalkyl, heteroaryl, and heteroarylalkyl each optionally substituted with 1, 2, 3, 4, or 5 substituents selected independently from the group consisting of C₁₋₆ acyl, C₁₋₆ acyloxy, C₂₋₆ alkenyl, C₁₋₆ alkoxy, C₁₋₆ alkyl, C₁₋₆ alkylcarboxamide, C₂₋₆ alkynyl, C₁₋₆ alkylsulfonamide, C₁₋₆ alkylsulfinyl, C₁₋₆ alkylsulfonyl, C₁₋₆ alkylthio, C₁₋₆ alkylureyl, amino, C₁₋₆ alkylamino, C₂₋₈ dialkylamino, carbo-C₁₋₆-alkoxy, carboxamide, carboxy, cyano, C₃₋₇ cycloalkyl, C₂₋₈ dialkylcarboxamide, C₂₋₈ dialkylsulfonamide, halogen, C₁₋₆ haloalkoxy, C₁₋₆ haloalkyl, C₁₋₆ haloalkylsulfinyl, C₁₋₆ haloalkylsulfonyl, C₁₋₆ haloalkylthio, hydroxyl, thiol, nitro, oxo, phenyl, and sulfonamide. In some embodiments, the “mono-valent-metabolically-labile group” is C₁₋₁₂ acyl, carbo-C₁₋₆-alkoxy, or C(—O)O-aryl, wherein the C₁₋₁₂ acyl, carbo-C₁₋₆-alkoxy, and —C(═O)O-aryl are each optionally substituted with 1, 2, 3, 4, or 5 substituents selected independently from the group consisting of C₁₋₆ alkylcarboxamide, amino, C₁₋₆ alkylamino, C₂₋₈ dialkylamino, C₁₋₆ alkylimino, C₁₋₆ alkylsulfinyl, C₁₋₆ alkylsulfonyl, C₁₋₆ alkylthio, halogen, nitro, and phenyl; or R^(4b) is —C(═O)OCR^(a)R^(b)OC(═O)R^(c), wherein R^(a), R^(b) and R^(c) are each independently selected from H, or C₁₋₆ alkyl. The groups illustrated are exemplary, not exhaustive, and one skilled in the art could prepare other known varieties of groups. In some cases, a “mono-valent-metabolically-labile group” (i.e., R^(4b)) can serve to improve efficacy or safety through improved oral bioavailability, or pharmacodynamic half-life, etc.

The term “in need of treatment” is intended to mean a judgment made by a caregiver (e.g. physician, nurse, nurse practitioner, etc. in the case of humans; veterinarian in the case of animals, including non-human mammals) that an individual or animal requires or will benefit from treatment. This judgment is made based on a variety of factors that are in the realm of a caregiver's expertise, but that includes the knowledge that the individual or animal is ill, or will become ill, as the result of a disease, condition or disorder that is treatable by the compounds of the invention. Accordingly, the compounds of the invention can be used in a protective or preventive manner; or compounds of the invention can be used to alleviate, inhibit or ameliorate the disease, condition or disorder.

The term “individual” is intended to mean any animal, including mammals, preferably mice, rats, other rodents, rabbits, dogs, cats, swine, cattle, sheep, horses, or primates, and most preferably humans.

The term “inverse agonists” is intended to mean moieties that bind the endogenous form of the receptor or to the constitutively activated form of the receptor, and which inhibit the baseline intracellular response initiated by the active form of the receptor below the normal base level of activity which is observed in the absence of agonists or partial agonists, or decrease GTP binding to membranes. Preferably, the baseline intracellular response is inhibited in the presence of the inverse agonist by at least 30%, more preferably by at least 50%, and most preferably by at least 75%, as compared with the baseline response in the absence of the inverse agonist.

The term “isolated” refers to material that is removed from its original environment (e.g., the natural environment if it is naturally occurring). For example, a metabolite that is formed from a parent compound present in a natural system (e.g. individual) is not isolated, but the same metabolite, separated from some or all of the coexisting materials in the natural system is considered isolated. In addition, the metabolite that is prepared by synthetic means is also considered isolated.

The term “modulate or modulating” is intended to mean an increase or decrease in the amount, quality, response or effect of a particular activity, function or molecule.

The term “pharmaceutical composition” is intended to mean a composition comprising at least one active ingredient; including but not limited to, salts, solvates and hydrates of compounds of Formula (Ia); whereby the composition is amenable to investigation for a specified, efficacious outcome in a mammal (for example, without limitation, a human). Those of ordinary skill in the art will understand and appreciate the techniques appropriate for determining whether an active ingredient has a desired efficacious outcome based upon the needs of the artisan.

The term “prodrug” as used herein refers to any compound that when administered to a biological system (e.g., in vivo in an individual, and the like) generates a compound of Formula (Ia), wherein R^(4a) and R^(4b) are both H, as a result of chemical reaction(s), enzyme catalyzed chemical reaction(s), and/or metabolic chemical reaction(s). In some embodiments, compounds of the present invention can be converted to “pro-drugs.” In some embodiments, “pro-drugs” refer to compounds that have been modified with specific chemical groups known in the art and when administered into an individual these groups undergo biotransformation to give the parent compound. Pro-drugs can thus be viewed as compounds of the invention containing one or more specialized non-toxic protective groups used in a transient manner to alter or to eliminate a property of the compound. In one general aspect, the “pro-drug” approach is utilized to facilitate oral absorption. A thorough discussion is provided in T. Higuchi and V. Stella, “Pro-drugs as Novel Delivery Systems,” Vol. 14 of the A.C.S. Symposium Series; and in Bioreversible Carriers in Drug Design, ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987, both of which are hereby incorporated by reference in their entirety.

The term “divalent-metabolically-labile group” as used herein refers to any group that comprises R^(4a) and R^(4b) together with the nitrogen to which they are bonded and following administration of a compound containing the group, is converted in vivo to a compound of Formula (Ia) wherein R^(4a) and R^(4b) are both H. The conversion of the “second metabolically-liable group” can be by metabolic and/or chemical processes and can occur in one step or through a series of two or more steps. Representative examples of a “divalent-metabolically-labile group” include, but are not limited to, when R^(4a) and R^(4b) together with the nitrogen to which they are both bonded form a heterocyclic group optionally substituted with 1, 2, 3, 4, or 5 substituents selected independently from the group consisting of C₁₋₆ acyl, C₁₋₆ acyloxy, C₂₋₆ alkenyl, C₁₋₆ alkoxy, C₁₋₆ alkyl, C₁₋₆ alkylcarboxamide, C₂₋₆ alkynyl, C₁₋₆ alkylsulfonamide, C₁₋₆ alkylsulfinyl, C₁₋₆ alkylsulfonyl, C₁₋₆ alkylthio, C₁₋₆ alkylureyl, amino, C₁₋₆ alkylamino, C₂₋₈ dialkylamino, carbo-C₁₋₆-alkoxy, carboxamide, carboxy, cyano, C₃₋₇ cycloalkyl, C₂₋₈ dialkylcarboxamide, C₂₋₈ dialkylsulfonamide, halogen, C₁₋₆ haloalkoxy, C₁₋₆ haloalkyl, C₁₋₆ haloalkylsulfinyl, C₁₋₆ haloalkylsulfonyl, C₁₋₆ haloalkylthio, hydroxyl, thiol, nitro, oxo, phenyl, thiooxo, and sulfonamide (such as, morpholin-4-yl, 2,5-dioxo-pyrrolidin-1-yl, and the like). The groups illustrated are exemplary, not exhaustive, and one skilled in the art could prepare other known varieties of groups. In some cases, a “divalent-metabolically-labile group” (i.e., related to when R^(4a) and R^(4b) together with the nitrogen to which they are both bonded) can serve to improve efficacy or safety through improved oral bioavailability, or pharmacodynamic half-life, etc.

The term “therapeutically effective amount” is intended to mean the amount of active compound or pharmaceutical agent that elicits the biological or medicinal response in a tissue, system, animal, individual or human that is being sought by a researcher, veterinarian, medical doctor or other clinician, which includes one or more of the following:

(1) Preventing the disease; for example, preventing a disease, condition or disorder in an individual that may be predisposed to the disease, condition or disorder but does not yet experience or display the pathology or symptomatology of the disease,

(2) Inhibiting the disease; for example, inhibiting a disease, condition or disorder in an individual that is experiencing or displaying the pathology or symptomatology of the disease, condition or disorder (i.e., arresting further development of the pathology and/or symptomatology), and

(3) Ameliorating the disease; for example, ameliorating a disease, condition or disorder in an individual that is experiencing or displaying the pathology or symptomatology of the disease, condition or disorder (i.e., reversing the pathology and/or symptomatology).

Additionally, individual compounds and chemical genera of the present invention, such as Formula (Ia) and related Formulae therefrom, encompass all pharmaceutically acceptable salts, solvates, and particularly hydrates, thereof.

It is understood that the present invention embraces each diastereomer, each enantiomer and mixtures thereof of each compound and generic Formulae disclosed herein just as if they were each individually disclosed with the specific stereochemical designation for each chiral atom, for example carbon. Separation of the individual isomers (such as, chiral HPLC, recrystallization of diastereomeric mixture, and the like) or selective synthesis (such as, enantiomeric selective synthesis, and the like) of the individual isomers is accomplished by application of various methods which are well known to practitioners in the art.

The compounds of the Formula (Ia) of the present invention can be prepared according to the general synthetic schemes in FIGS. 1 through 8 ad well as relevant published literature procedures that are used by one skilled in the art. Exemplary reagents and procedures for these reactions appear hereinafter in the working Examples. Protection and deprotection may be carried out by procedures generally known in the art (see, for example, Greene, T. W. and Wuts, P. G. M., Protecting Groups in Organic Synthesis, 3^(rd) Edition, 1999 [Wiley]; incorporated herein by reference in its entirety).

Indications and Methods of Treatment

In addition to the foregoing beneficial uses for the modulators of 5-HT_(2A) receptor activity disclosed herein, the compounds disclosed herein are believed to be useful in the treatment of several additional diseases and disorders, and in the amelioration of symptoms thereof. Without limitation, these include the following:

1. Antiplatelet Therapies (Conditions Related to Platelet Aggregation):

Antiplatelet agents (antiplatelets) are prescribed for a variety of conditions. For example, in coronary artery disease they are used to help prevent myocardial infarction or stroke in patients who are at risk of developing obstructive blood clots (e.g., coronary thrombosis).

In a myocardial infarction (heart attack), the heart muscle does not receive enough oxygen-rich blood as a result of a blockage in the coronary blood vessels. If taken while an attack is in progress or immediately afterward (preferably within 30 minutes), antiplatelets can reduce the damage to the heart.

A transient ischemic attack (“TIA” or “mini-stroke”) is a brief interruption of oxygen flow to the brain due to decreased blood flow through arteries, usually due to an obstructing blood clot. Antiplatelet drugs have been found to be effective in preventing TIAs.

Angina is a temporary and often recurring chest pain, pressure or discomfort caused by inadequate oxygen-rich blood flow (ischemia) to some parts of the heart. In patients with angina, antiplatelet therapy can reduce the effects of angina and the risk of myocardial infarction.

Stroke is an event in which the brain does not receive enough oxygen-rich blood, usually due to blockage of a cerebral blood vessel by a blood clot. In high-risk patients, taking antiplatelets regularly has been found to prevent the formation of blood clots that cause first or second strokes.

Angioplasty is a catheter based technique used to open arteries obstructed by a blood clot. Whether or not stenting is performed immediately after this procedure to keep the artery open, antiplatelets can reduce the risk of forming additional blood clots following the procedure(s).

Coronary bypass surgery is a surgical procedure in which an artery or vein is taken from elsewhere in the body and grafted to a blocked coronary artery, rerouting blood around the blockage and through the newly attached vessel. After the procedure, antiplatelets can reduce the risk of secondary blood clots.

Atrial fibrillation is the most common type of sustained irregular heart rhythm (arrhythmia). Atrial fibrillation affects about two million Americans every year. In atrial fibrillation, the atria (the heart's upper chambers) rapidly fire electrical signals that cause them to quiver rather than contract normally. The result is an abnormally fast and highly irregular heartbeat. When given after an episode of atrial fibrillation, antiplatelets can reduce the risk of blood clots forming in the heart and traveling to the brain (embolism).

5-HT_(2A) receptors are expressed on smooth muscle of blood vessels and 5-HT secreted by activated platelets causes vasoconstriction as well as activation of additional platelets during clotting. There is evidence that a 5-HT_(2A) inverse agonist will inhibit platelet aggregation and thus be a potential treatment as an antiplatelet therapy (see Satimura, K, et al., Clin Cardiol 2002 Jan. 25 (1):28-32; and Wilson, H. C et al., Thromb Haemost 1991 Sep. 2; 66(3):355-60).

5-HT_(2A) inverse agonists can be used to treat, for example, claudication or peripheral artery disease as well as cardiovascular complications (see Br. Med. J. 298: 424-430, 1989), Arterial thrombosis (see, Pawlak, D. et al. Thrombosis Research 90: 259-270, 1998), atherosclerosis (see, Hayashi, T. et al. Atherosclerosis 168: 23-31, 2003), vasoconstriction, caused by serotonin (see, Fujiwara, T. and Chiba, S. Journal of Cardiovascular Pharmacology 26: 503-510, 1995), restenosis of arteries following angioplasty or stent placement (see, Fujita, M. et al. Am Heart J. 145:e16 2003). It can also be used alone or in combination with thrombolytic therapy, for example, tPA (see, Yamashita, T. et al. Haemostasis 30:321-332, 2000), to provide cardioprotection following MI or postischemic myocardial dysfunction (see, Muto, T. et al. Mol. Cell. Biochem. 272: 119-132, 2005) or protection from ischemic injury during percutaneous coronary intervention (see, Horibe, E. Circulation Research 68: 68-72, 2004), and the like, including complications resulting therefrom.

5-HT_(2A) inverse antagonists can increase circulating adiponectin in patients, suggesting that they would also be useful in protecting patients against indications that are linked to adiponectin, for example, myocardial ischemia reperfusion injury and artherosclerosis (see Nomura, Shosaku, et al. Blood Coagulation and Fibrinolysis 2005, 16, 423-428).

The 5-HT_(2A) inverse agonists disclosed herein provide beneficial improvement in microcirculation to patients in need of antiplatelet therapy by antagonizing the vasoconstrictive products of the aggregating platelets in, for example and not limited to the indications described above. Accordingly, in some embodiments, the present invention provides methods for reducing platelet aggregation in a patient in need thereof comprising administering to the patient a composition comprising a 5-HT_(2A) inverse agonist disclosed herein. In further embodiments, the present invention provides methods for treating coronary artery disease, myocardial infarction, transient ischemic attack, angina, stroke, atrial fibrillation, or a symptom of any of the foregoing in a patient in need of the treatment, comprising administering to the patient a composition comprising a 5-HT_(2A) inverse agonist disclosed herein.

In further embodiments, the present invention provides methods for reducing risk of blood clot formation in an angioplasty or coronary bypass surgery patient, or a patient suffering from atrial fibrillation, comprising administering to the patient a composition comprising a 5-HT_(2A) inverse agonist disclosed herein at a time where such risk exists.

One aspect of the present invention provides a therapeutic agent for treating indications associated with the pathophysiology of platelet aggregation used in combination with compounds of the present invention as disclosed herein. Accordingly, compounds of the present invention can be used alone or in combination with other therapeutic agent(s), such as, thromboxane A2 blocker (aspirin and the like), and ADP-mediated platelet aggregation inhibitor (ticlopidine, elopidogrel, and the like) either administered together or separately.

2. Asthma

5-HT (5-hydroxytryptamine) has been linked to the pathophysiology of acute asthma (see Cazzola, M. and Matera, M. G., TIPS, 2000, 21, 13; and De Bie, J. J. et al., British J. Pharm., 1998, 124, 857-864). The compounds of the present invention disclosed herein are useful in the treatment of asthma, and the treatment of the symptoms thereof. Accordingly, in some embodiments, the present invention provides methods for treating asthma in a patient in need of the treatment, comprising administering to the patient a composition comprising a 5-HT_(2A) inverse agonist disclosed herein. In further embodiments, methods are provided for treating a symptom of asthma in a patient in need of the treatment, comprising administering to the patient a composition comprising a 5-HT_(2A) inverse agonist disclosed herein.

3. Agitation

Agitation is a well-recognized behavioral syndrome with a range of symptoms, including hostility, extreme excitement, poor impulse control, tension and uncooperativeness (See Cohen-Mansfield J, and Billig, N., (1986), Agitated Behaviors in the Elderly. I. A Conceptual Review. J. Am Geriatr Soc 34(10): 711-721).

Agitation is a common occurrence in the elderly and often associated with dementia such as those caused by Alzheimer's disease, Lewy body, Parkinson's, and Huntington's, which are degenerative diseases of the nervous system and by diseases that affect blood vessels, such as stroke, or multi-infarct dementia, which is caused by multiple strokes in the brain can also induce dementia. Alzheimer's disease accounts for approximately 50 to 70% of all dementias (See Koss E, et al., (1997), Assessing patterns of agitation in Alzheimer's disease patients with the Cohen-Mansfield Agitation Inventory. The Alzheimer's Disease Cooperative Study. Alzheimer Dis Assoc Disord 11(suppl 2):S45-S50).

An estimated five percent of people aged 65 and older and up to 20 percent of those aged 80 and older are affected by dementia; of these sufferers, nearly half exhibit behavioral disturbances, such as agitation, wandering and violent outbursts.

Agitated behaviors can also be manifested in cognitively intact elderly people and by those with psychiatric disorders other than dementia.

Agitation is often treated with antipsychotic medications such as haloperidol in nursing home and other assisted care settings. There is emerging evidence that agents acting at the 5-HT_(2A) receptors in the brain have the effects of reducing agitation in patients, including Alzheimer's dementia (See Katz, I. R., et al., J Clin Psychiatry 1999 February, 60(2):107-115; and Street, J. S., et al., Arch Gen Psychiatry 2000 October, 57(10):968-976).

The compounds of the invention disclosed herein are useful for treating agitation and symptoms thereof. Thus, in some embodiments, the present invention provides methods for treating agitation in a patient in need of such treatment comprising administering to the patient a composition comprising a 5-HT_(2A) inverse agonist disclosed herein. In some embodiments, the agitation is due to a psychiatric disorder other than dementia. In some embodiments, the present invention provides methods for treatment of agitation or a symptom thereof in a patient suffering from dementia comprising administering to the patient a composition comprising a 5-HT_(2A) inverse agonist disclosed herein. In some embodiments of such methods, the dementia is due to a degenerative disease of the nervous system, for example and without limitation, Alzheimers disease, Lewy body, Parkinson's disease, and Huntington's disease, or dementia due to diseases that affect blood vessels, including, without limitation, stroke and multi-infarct dementia. In some embodiments, methods are provided for treating agitation or a symptom thereof in a patient in need of such treatment, where the patient is a cognitively intact elderly patient, comprising administering to the patient a composition comprising a 5-HT_(2A) inverse agonist disclosed herein.

4. Add-on Therapy to Haloperidol in the Treatment of Schizophrenia and Other Disorders:

Schizophrenia is a psychopathic disorder of unknown origin, which usually appears for the first time in early adulthood and is marked by a number of characteristics, psychotic symptoms, progression, phasic development and deterioration in social behavior and professional capability in the region below the highest level ever attained. Characteristic psychotic symptoms are disorders of thought content (multiple, fragmentary, incoherent, implausible or simply delusional contents or ideas of persecution) and of mentality (loss of association, flight of imagination, incoherence up to incomprehensibility), as well as disorders of perceptibility (hallucinations), of emotions (superficial or inadequate emotions), of self-perception, of intentions and impulses, of interhuman relationships, and finally psychomotoric disorders (such as catatonia). Other symptoms are also associated with this disorder. (See, American Statistical and Diagnostic Handbook).

Haloperidol (Haldol) is a potent dopamine D₂ receptor antagonist. It is widely prescribed for acute schizophrenic symptoms, and is very effective for the positive symptoms of schizophrenia. In accordance with some methods of the invention, adding a 5-HT_(2A) inverse agonist concomitantly with Haldol will provide benefits including the ability to use a lower dose of Haldol without losing its effects on positive symptoms, while reducing or eliminating its inductive effects on negative symptoms, and prolonging relapse to the patient's next schizophrenic event.

5. Sleep Disorders

It is reported in the National Sleep Foundation's 2002 Sleep In America Poll, more than one-half of the adults surveyed (58%) report having experienced one or more symptoms of insomnia at least a few nights a week in the past year. Additionally, about three in ten (35%) say they have experienced insomnia-like symptoms every night or almost every night.

The normal sleep cycle and sleep architecture can be disrupted by a variety of organic causes as well as environmental influences. According to the International Classification of Sleep Disorders, there are over 80 recognized sleep disorders. Of these, compounds of the present invention are effective, for example, in any one or more of the following sleep disorders (ICSD—International Classification of Sleep Disorders: Diagnostic and Coding Manual. Diagnostic Classification Steering Committee, American Sleep Disorders Association, 1990):

The effects of sleep deprivation are more than excessive daytime sleepiness. Chronic insomniacs report elevated levels of stress, anxiety, depression and medical illnesses (National Institutes of Health, National Heart, Lung, and Blood Institute, Insomnia Facts Sheet, October 1995). Preliminary evidence suggests that having a sleep disorder that causes significant loss of sleep may contribute to increased susceptibility to infections due to immunosuppression, cardiovascular complications such as hypertension, cardiac arrhythmias, stroke, and myocardial infarction, compromised glucose tolerance, increased obesity and metabolic syndrome. Compounds of the present invention are useful to prevent or alleviate these complications by improving sleep quality.

The most common class of medications for the majority of sleep disorders are the benzodiazepines, but the adverse effect profile of benzodiazepines include daytime sedation, diminished motor coordination, and cognitive impairments. Furthermore, the National Institutes of Health Consensus conference on Sleeping Pills and Insomnia in 1984 have developed guidelines discouraging the use of such sedative-hypnotics beyond 4-6 weeks because of concerns raised over drug misuse, dependency, withdrawal and rebound insomnia. Therefore, it is desirable to have a pharmacological agent for the treatment of insomnia, which is more effective and/or has fewer side effects than those currently used. In addition, benzodiazepines are used to induce sleep, but have little to no effect on the maintenance of sleep, sleep consolidation or slow wave sleep. Therefore, sleep maintenance disorders are not currently well treated.

Clinical studies with agents of a similar mechanism of action as are compounds of the present invention have demonstrated significant improvements on objective and subjective sleep parameters in normal, healthy volunteers as well as patients with sleep disorders and mood disorders [Sharpley A L, et al. Slow Wave Sleep in Humans: Role of 5-HT_(2A) and 5-HT_(2C) Receptors. Neuropharmacology, 1994, Vol. 33(3/4):467-71; Winokur A, et al. Acute Effects of Mirtazapine on Sleep Continuity and Sleep Architecture in Depressed Patients: A Pilot Study. Soc of Biol Psych, 2000, Vol. 48:75-78; and Landolt H P, et al. Serotonin-2 Receptors and Human Sleep: Effect of Selective Antagonist on EEG Power Spectra. Neuropsychopharmacology, 1999, Vol. 21(3):455-66].

Some sleep disorders are sometimes found in conjunction with other conditions and accordingly those conditions are treatable by compounds of Formula (Ia). For example, but not limited to, patients suffering from mood disorders typically suffer from a sleep disorder that can be treatable by compounds of Formula (Ia). Having one pharmacological agent which treats two or more existing or potential conditions, as does the present invention, is more cost effective, leads to better compliance and has fewer side effects than taking two or more agents.

It is an object of the present invention to provide a therapeutic agent for the use in treating Sleep Disorders. It is another object of the present invention to provide one pharmaceutical agent, which may be useful in treating two or more conditions wherein one of the conditions is a sleep disorder. Compounds of the present invention described herein may be used alone or in combination with a mild sleep inducer, such as, a sedating antihistamine (diphenhydramine, chloropheniramine, bromopheniramine and the like), GABA-A receptor modulators (Ambien, Sonata, Indiplon, Gaboxadol, and the like), melatonin agonists (ML1 receptor agonist, such as Ramelteon and the like), sedating antidepressants (such as a tricyclic antidepressant, doxepine and the like), and benzodiazepines (diazepam and the like) and either administered together or separately.

Sleep Architecture:

Sleep comprises two physiological states: Non rapid eye movement (NREM) and rapid eye movement (REM) sleep. NREM sleep consists of four stages, each of which is characterized by progressively slower brain wave patterns, with the slower patterns indicating deeper sleep. So called delta sleep, stages 3 and 4 of NREM sleep, is the deepest and most refreshing type of sleep. Many patients with sleep disorders are unable to adequately achieve the restorative sleep of stages 3 and 4. In clinical terms, patients' sleep patterns are described as fragmented, meaning the patient spends a lot of time alternating between stages 1 and 2 (semi-wakefulness) and being awake and very little time in deep sleep. As used herein, the term “fragmented sleep architecture” means an individual, such as a sleep disorder patient, spends the majority of their sleep time in NREM sleep stages 1 and 2, lighter periods of sleep from which the individual can be easily aroused to a waking state by limited external stimuli. As a result, the individual cycles through frequent bouts of light sleep interrupted by frequent awakenings throughout the sleep period. Many sleep disorders are characterized by a fragmented sleep architecture. For example, many elderly patients with sleep complaints have difficulty achieving long bouts of deep refreshing sleep (NREM stages 3 and 4) and instead spend the majority of their sleep time in NREM sleep stages 1 and 2.

In contrast to fragmented sleep architecture, as used herein the term “sleep consolidation” means a state in which the number of NREM sleep bouts, particularly Stages 3 and 4, and the length of those sleep bouts are increased, while the number and length of waking bouts are decreased. In essence, the architecture of the sleep disorder patient is consolidated to a sleeping state with increased periods of sleep and fewer awakenings during the night and more time is spent in slow wave sleep (Stages 3 and 4) with fewer oscillation Stage 1 and 2 sleep. Compounds of the present invention can be effective in consolidating sleep patterns so that the patient with previously fragmented sleep can now achieve restorative, delta-wave sleep for longer, more consistent periods of time.

As sleep moves from stage 1 into later stages, heart rate and blood pressure drop, metabolic rate and glucose consumption fall, and muscles relax. In normal sleep architecture, NREM sleep makes up about 75% of total sleep time; stage 1 accounting for 5-10% of total sleep time, stage 2 for about 45-50%, stage 3 approximately 12%, and stage 4 13-15%. About 90 minutes after sleep onset, NREM sleep gives way to the first REM sleep episode of the night. REM makes up approximately 25% of total sleep time. In contrast to NREM sleep, REM sleep is characterized by high pulse, respiration, and blood pressure, as well as other physiological patterns similar to those seen in the active waking stage. Hence, REM sleep is also known as “paradoxical sleep.” Sleep onset occurs during NREM sleep and takes 10-20 minutes in healthy young adults. The four stages of NREM sleep together with a REM phase form one complete sleep cycle that is repeated throughout the duration of sleep, usually four or five times. The cyclical nature of sleep is regular and reliable; a REM period occurs about every 90 minutes during the night. However, the first REM period tends to be the shortest, often lasting less than 10 minutes, whereas the later REM periods may last up to 40 minutes. With aging, the time between retiring and sleep onset increases and the total amount of night-time sleep decreases because of changes in sleep architecture that impair sleep maintenance as well as sleep quality. Both NREM (particularly stages 3 and 4) and REM sleep are reduced. However, stage 1 NREM sleep, which is the lightest sleep, increases with age.

As used herein, the term “delta power” means a measure of the duration of EEG activity in the 0.5 to 3.5 Hz range during NREM sleep and is thought to be a measure of deeper, more refreshing sleep. Delta power is hypothesized to be a measure of a theoretical process called Process S and is thought to be inversely related to the amount of sleep an individual experiences during a given sleep period. Sleep is controlled by homeostatic mechanisms; therefore, the less one sleeps the greater the drive to sleep. It is believed that Process S builds throughout the wake period and is discharged most efficiently during delta power sleep. Delta power is a measure of the magnitude of Process S prior to the sleep period. The longer one stays awake, the greater Process S or drive to sleep and thus the greater the delta power during NREM sleep. However, individuals with sleep disorders have difficulty achieving and maintaining delta wave sleep, and thus have a large build-up of Process S with limited ability to discharge this buildup during sleep. 5-HT_(2A) agonists tested preclinically and clinically mimic the effect of sleep deprivation on delta power, suggesting that subjects with sleep disorders treated with a 5-HT_(2A) inverse agonist or antagonist will be able to achieve deeper more refreshing sleep. These same effects have not been observed with currently marketed pharmacotherapies. In addition, currently marketed pharmacotherapies for sleep have side effects such as hangover effects or addiction that are associated with the GABA receptor. 5-HT_(2A) inverse agonists do not target the GABA receptor and so these side effects are not a concern.

Subjective and Objective Determinations of Sleep Disorders:

There are a number of ways to determine whether the onset, duration or quality of sleep (e.g. non-restorative or restorative sleep) is impaired or improved. One method is a subjective determination of the patient, e.g., do they feel drowsy or rested upon waking. Other methods involve the observation of the patient by another during sleep, e.g., how long it takes the patient to fall asleep, how many times does the patient wake up during the night, how restless is the patient during sleep, etc. Another method is to objectively measure the stages of sleep using polysomnography.

Polysomnography is the monitoring of multiple electrophysiological parameters during sleep and generally includes measurement of EEG activity, electroculographic activity and electromyographic activity, as well as other measurements. These results, along with observations, can measure not only sleep latency (the amount of time required to fall asleep), but also sleep continuity (overall balance of sleep and wakefulness) and sleep consolidation (percent of sleeping time spent in delta-wave or restorative sleep) which may be an indication of the quality of sleep.

There are five distinct sleep stages, which can be measured by polysomnography: rapid eye movement (REM) sleep and four stages of non-rapid eye movement (NREM) sleep (stages 1, 2, 3 and 4). Stage 1 NREM sleep is a transition from wakefulness to sleep and occupies about 5% of time spent asleep in healthy adults. Stage 2 NREM sleep, which is characterized by specific EEG waveforms (sleep spindles and K complexes), occupies about 50% of time spent asleep. Stages 3 and 4 NREM sleep (also known collectively as slow-wave sleep and delta-wave sleep) are the deepest levels of sleep and occupy about 10-20% of sleep time. REM sleep, during which the majority of vivid dreams occur, occupies about 20-25% of total sleep.

These sleep stages have a characteristic temporal organization across the night. NREM stages 3 and 4 tend to occur in the first one-third to one-half of the night and increase in duration in response to sleep deprivation. REM sleep occurs cyclically through the night. Alternating with NREM sleep about every 80-100 minutes. REM sleep periods increase in duration toward the morning. Human sleep also varies characteristically across the life span. After relative stability with large amounts of slow-wave sleep in childhood and early adolescence, sleep continuity and depth deteriorate across the adult age range. This deterioration is reflected by increased wakefulness and stage 1 sleep and decreased stages 3 and 4 sleep.

In addition, the compounds of the invention can be useful for the treatment of the sleep disorders characterized by excessive daytime sleepiness such as narcolepsy. Inverse agonists at the serotonin 5-HT_(2A) receptor improve the quality of sleep at nighttime which can decrease excessive daytime sleepiness.

Accordingly, another aspect of the present invention relates to the therapeutic use of compounds of the present invention for the treatment of Sleep Disorders. Compounds of the present invention are potent inverse agonists at the serotonin 5-HT_(2A) receptor and can be effective in the treatment of Sleep Disorders by promoting one or more of the following: reducing the sleep onset latency period (measure of sleep induction), reducing the number of nighttime awakenings, and prolonging the amount of time in delta-wave sleep (measure of sleep quality enhancement and sleep consolidation) without effecting REM sleep. In addition, compounds of the present invention can be effective either as a monotherapy or in combination with sleep inducing agents, for example but not limited to, antihistamines.

6. Diabetic-Related Pathologies:

Although hyperglycemia is the major cause for the pathogenesis of diabetic complications such as diabetic peripheral neuropathy (DPN), diabetic nephropathy (DN) and diabetic retinopathy (DR), increased plasma serotonin concentration in diabetic patients has also been implicated to play a role in disease progression (Pietraszek, M. H., et al. Thrombosis Res. 1992, 66(6), 765-74; and Andrzejewska-Buczko J, et al., Klin Oczna. 1996; 98(2), 101-4). Serotonin is believed to play a role in vasospasm and increased platelet aggregability. Improving microvascular blood flow is able to benefit diabetic complications.

A recent study by Cameron and Cotter in Naunyn Schmiedebergs Arch Pharmacol. 2003 June; 367(6):607-14, used a 5-HT_(2A) antagonist experimental drug AT-1015, and other non-specific 5-HT_(2A) antagonists including ritanserin and sarpogrelate. These studies found that all three drugs were able to produce a marked correction (82.6-99.7%) of a 19.8% sciatic motor conduction deficit in diabetic rats. Similarly, 44.7% and 14.9% reductions in sciatic endoneurial blood flow and saphenous sensory conduction velocity were completely reversed.

In a separate patient study, sarpogrelate was evaluated for the prevention of the development or progression of diabetic nephropathy (Takahashi, T., et al., Diabetes Res Clin Pract. 2002 November; 58(2):123-9). In the trial of 24 months of treatment, sarpogrelate significantly reduced urinary albumin excretion level.

7. Glaucoma

Topical ocular administration of 5-HT2 receptor antagonists result in a decrease in intra ocular pressure (IOP) in monkeys (Chang et al., J. Ocul Pharmacol 1:137-147 (1985)) and humans (Mastropasqua et al., Acta Ophthalmol Scand Suppl 224:24-25 (1997)) indicating utility for similar compounds such as 5-HT_(2A) inverse agonists in the treatment of ocular hypertension associated with glaucoma. The 5-HT2 receptor antagonist ketanserin (Mastropasqua supra) and sarpogrelate (Takenaka et al., Investig Ophthalmol V is Sci 36:S734 (1995)) have been shown to significantly lower IOP in glaucoma patients.

8. Progressive Multifocal Leukoencephalopathy

Progressive multifocal leukoencephalopathy (PML) is a lethal demyelinating disease caused by an opportunistic viral infection of oligodendrocytes in immunocompromised patients. The causative agent is JC virus, a ubiquitous papovavirus that infects the majority of the population before adulthood and establishes a latent infection in the kidney. In immunocompromised hosts, the virus can reactivate and productively infect oligodendrocytes. This previously rare condition, until 1984 reported primarily in persons with underlying lymphoproliferative disorders, is now more common because it occurs in 4% of patients with AIDS. Patients usually present with relentlessly progressive focal neurologic defects, such as hemiparesis or visual field deficits, or with alterations in mental status. On brain MRI, one or more white matter lesions are present; they are hyperintense on T2-weighted images and hypointense on T1-weighted images. There is no mass effect, and contrast enhancement is rare. Diagnosis can be confirmed by brain biopsy, with demonstration of virus by in situ hybridization or immunocytochemistry. Polymerase chain reaction amplification of JC virus sequences from the CSF can confirm diagnosis without the need for biopsy [see, e.g., Antinori et al., Neurology (1997) 48:687-694; Berger and Major, Seminars in Neurology (1999) 19:193-200; and Portegies, et al., Eur. J. Neurol. (2004) 11:297-304]. Currently, there is no effective therapy. Survival after diagnosis is about 3 to 5 months in AIDS patients.

JC virus enters cells by receptor-mediated clathrin-dependent endocytosis. Binding of JC virus to human glial cells (e.g., oligodendrocytes) induces an intracellular signal that is critical for entry and infection by a ligand-inducible clathrin-dependent mechanism [Querbes et al., J Virology (2004) 78:250-256]. Recently, 5-HT_(2A) was shown to be the receptor on human glial cells mediating infectious entry of JC virus by clathrin-dependent endocytosis [Elphick et al., Science (2004) 306:1380-1383]. 5-HT_(2A) antagonists, including ketanserin and ritanserin, inhibited JC virus infection of human glial cells. Ketanserin and ritanserin have inverse agonist activity at 5-HT_(2A).

5-HT_(2A) antagonists including inverse agonists have been contemplated to be useful in the treatment of PML [Elphick et al., Science (2004) 306:1380-1383]. Prophylactic treatment of HIV-infected patients with 5-HT_(2A) antagonists is envisioned to prevent the spread of JC virus to the central nervous system and the development of PML. Aggressive therapeutic treatment of patients with PML is envisioned to reduce viral spread within the central nervous system and prevent additional episodes of demyelination.

In some embodiments, methods are provided for treating progressive multifocal leukoencephalopathy in a patient in need of such treatment, comprising administering to the patient a composition comprising a 5-HT_(2A) inverse agonist disclosed herein.

9. Hypertension

Serotonin has been observed to play an important role in the regulation of vascular tone, vasoconstriction, and pulmonary hypertension (see, Deuchar, G. et al. Pulm. Pharmacol. Ther. 18(1):23-31. 2005; and Marcos, E. et al. Circ. Res. 94(9):1263-70 2004). Ketanserin, a 5-HT2A inverse agonist, have been demonstrated to protect against circulatory shocks, intracranial hypertension, and cerebral ischemia during heatstroke (see, Chang, C. et al. Shock 24(4): 336-340 2005); and to stabilize blood pressure in spontaneously hypertensive rats (see, Miao, C. Clin. Exp. Pharmacol. Physiol. 30(3): 189-193). Mainserin, a 5-HT_(2A) inverse agonist, has been shown to prevent DOCA-salt induced hypertension in rats (see, Silva, A. Eur, J. Pharmacol. 518(2-3): 152-7 2005).

10. Pain

5-HT_(2A) inverse agonists are also effective for the treatment of pain. Sarpogrelate has been observed to provide a significant analgesic effect both on thermal induced pain in rats after intraperitoneal administration and on inflammatory pain in rats after either intrathecal or intraperitoneal administration (see, Nishiyama, T. Eur. J. Pharmacol. 516:18-22 2005). This same 5-HT_(2A) inverse agonist in humans has been shown to be an effective treatment for lower back pain, leg pain and numbness associated with sciatica brought on by lumbar disc herniation (see, Kanayama, M. et al. J. Neurosurg: Spine 2:441-446 2005).

Pharmaceutical Compositions

A further aspect of the present invention pertains to pharmaceutical compositions comprising one or more compounds as described herein and one or more pharmaceutically acceptable carriers. Some embodiments pertain to pharmaceutical compositions comprising a compound of the present invention and a pharmaceutically acceptable carrier.

Some embodiments of the present invention include a method of producing a pharmaceutical composition comprising admixing at least one compound according to any of the compound embodiments disclosed herein and a pharmaceutically acceptable carrier.

Formulations may be prepared by any suitable method, typically by uniformly mixing the active compound(s) with liquids or finely divided solid carriers, or both, in the required proportions, and then, if necessary, forming the resulting mixture into a desired shape.

Conventional excipients, such as binding agents, fillers, acceptable wetting agents, tabletting lubricants, and disintegrants may be used in tablets and capsules for oral administration. Liquid preparations for oral administration may be in the form of solutions, emulsions, aqueous or oily suspensions, and syrups. Alternatively, the oral preparations may be in the form of dry powder that can be reconstituted with water or another suitable liquid vehicle before use. Additional additives such as suspending or emulsifying agents, non-aqueous vehicles (including edible oils), preservatives, and flavorings and colorants may be added to the liquid preparations. Parenteral dosage forms may be prepared by dissolving the compound of the invention in a suitable liquid vehicle and filter sterilizing the solution before filling and sealing an appropriate vial or ampoule. These are just a few examples of the many appropriate methods well known in the art for preparing dosage forms.

A compound of the present invention can be formulated into pharmaceutical compositions using techniques well known to those in the art. Suitable pharmaceutically-acceptable carriers, outside those mentioned herein, are known in the art; for example, see Remington, The Science and Practice of Pharmacy, 20th Edition, 2000, Lippincott Williams & Wilkins, (Editors: Gennaro, A. R., et al.).

While it is possible that, for use in the treatment, a compound of the invention may, in an alternative use, be administered as a raw or pure chemical, it is preferable however to present the compound or active ingredient as a pharmaceutical formulation or composition further comprising a pharmaceutically acceptable carrier.

The invention thus further provides pharmaceutical formulations comprising a compound of the invention or a pharmaceutically acceptable salt or derivative thereof together with one or more pharmaceutically acceptable carriers thereof and/or prophylactic ingredients. The carriers) must be “acceptable” in the sense of being compatible with the other ingredients of the formulation and not overly deleterious to the recipient thereof.

Pharmaceutical formulations include those suitable for oral, rectal, nasal, topical (including buccal and sub-lingual), vaginal or parenteral (including intramuscular, sub-cutaneous and intravenous) administration or in a form suitable for administration by inhalation, insufflation or by a transdermal patch. Transdermal patches dispense a drug at a controlled rate by presenting the drug for absorption in an efficient manner with a minimum of degradation of the drug. Typically, transdermal patches comprise an impermeable backing layer, a single pressure sensitive adhesive and a removable protective layer with a release liner. One of ordinary skill in the art will understand and appreciate the techniques appropriate for manufacturing a desired efficacious transdermal patch based upon the needs of the artisan.

The compounds of the invention, together with a conventional adjuvant, carrier, or diluent, may thus be placed into the form of pharmaceutical formulations and unit dosages thereof, and in such form may be employed as solids, such as tablets or filled capsules, or liquids such as solutions, suspensions, emulsions, elixirs, gels or capsules filled with the same, all for oral use, in the form of suppositories for rectal administration; or in the form of sterile injectable solutions for parenteral (including subcutaneous) use. Such pharmaceutical compositions and unit dosage forms thereof may comprise conventional ingredients in conventional proportions, with or without additional active compounds or principles, and such unit dosage forms may contain any suitable effective amount of the active ingredient commensurate with the intended daily dosage range to be employed.

For oral administration, the pharmaceutical composition may be in the form of, for example, a tablet, capsule, suspension or liquid. The pharmaceutical composition is preferably made in the form of a dosage unit containing a particular amount of the active ingredient. Examples of such dosage units are capsules, tablets, powders, granules or a suspension, with conventional additives such as lactose, mannitol, corn starch or potato starch; with binders such as crystalline cellulose, cellulose derivatives, acacia, corn starch or gelatins; with disintegrators such as corn starch, potato starch or sodium carboxymethyl-cellulose; and with lubricants such as talc or magnesium stearate. The active ingredient may also be administered by injection as a composition wherein, for example, saline, dextrose or water may be used as a suitable pharmaceutically acceptable carrier.

Compounds of the present invention or a solvate or physiologically functional derivative thereof can be used as active ingredients in pharmaceutical compositions, specifically as 5-HT_(2A) receptor modulators. By the term “active ingredient” is defined in the context of a “pharmaceutical composition” and shall mean a component of a pharmaceutical composition that provides the primary pharmacological effect, as opposed to an “inactive ingredient” which would generally be recognized as providing no pharmaceutical benefit.

The dose when using the compounds of the present invention can vary within wide limits, as is customary and is known to the physician, it is to be tailored to the individual conditions in each individual case. It depends, for example, on the nature and severity of the illness to be treated, on the condition of the patient, on the compound employed or on whether an acute or chronic disease state is treated or prophylaxis is conducted or on whether further active compounds are administered in addition to the compounds of the present invention. Representative doses of the present invention include, but are not limited to, about 0.001 mg to about 5000 mg, about 0.001 mg to about 2500 mg, about 0.001 mg to about 1000 mg, 0.001 mg to about 500 mg, 0.001 mg to about 250 mg, about 0.001 mg to 100 mg, about 0.001 mg to about 50 mg, and about 0.001 mg to about 25 mg. Multiple doses may be administered during the day, especially when relatively large amounts are deemed to be needed, for example 2, 3 or 4, doses. Depending on the individual and as deemed appropriate from the patient's physician or care-giver it may be necessary to deviate upward or downward from the doses described herein.

The amount of active ingredient, or an active salt or derivative thereof, required for use in treatment will vary not only with the particular salt selected but also with the route of administration, the nature of the condition being treated and the age and condition of the patient and will ultimately be at the discretion of the attendant physician or clinician. In general, one skilled in the art understands how to extrapolate in vivo data obtained in a model system, typically an animal model, to another, such as a human. In some circumstances, these extrapolations may merely be based on the weight of the animal model in comparison to another, such as a mammal, preferably a human, however, more often, these extrapolations are not simply based on weights, but rather incorporate a variety of factors. Representative factors include the type, age, weight, sex, diet and medical condition of the patient, the severity of the disease, the route of administration, pharmacological considerations such as the activity, efficacy, pharmacokinetic and toxicology profiles of the particular compound employed, whether a drug delivery system is utilized, or whether an acute or chronic disease state is being treated or prophylaxis is conducted or on whether further active compounds are administered in addition to the compounds of the present invention and as part of a drug combination. The dosage regimen for treating a disease condition with the compounds and/or compositions of this invention is selected in accordance with a variety factors as cited above. Thus, the actual dosage regimen employed may vary widely and therefore may deviate from a preferred dosage regimen and one skilled in the art will recognize that dosage and dosage regimen outside these typical ranges can be tested and, where appropriate, may be used in the methods of this invention.

The desired dose may conveniently be presented in a single dose or as divided doses administered at appropriate intervals, for example, as two, three, four or more sub-doses per day. The sub-dose itself may be further divided, e.g., into a number of discrete loosely spaced administrations. The daily dose can be divided, especially when relatively large amounts are administered as deemed appropriate, into several, for example 2, 3 or 4, part administrations. If appropriate, depending on individual behavior, it may be necessary to deviate upward or downward from the daily dose indicated.

The compounds of the present invention can be administrated in a wide variety of oral and parenteral dosage forms. It will be obvious to those skilled in the art that the following dosage forms may comprise, as the active component, either a compound of the invention or a pharmaceutically acceptable salt of a compound of the invention.

For preparing pharmaceutical compositions from the compounds of the present invention, the selection of a suitable pharmaceutically acceptable carrier can be either solid, liquid or a mixture of both. Solid form preparations include powders, tablets, pills, capsules, cachets, suppositories, and dispersible granules. A solid carrier can be one or more substances which may also act as diluents, flavouring agents, solubilizers, lubricants, suspending agents, binders, preservatives, tablet disintegrating agents, or an encapsulating material.

In powders, the carrier is a finely divided solid which is in a mixture with the finely divided active component.

In tablets, the active component is mixed with the carrier having the necessary binding capacity in suitable proportions and compacted to the desire shape and size.

The powders and tablets may contain varying percentage amounts of the active compound. A representative amount in a powder or tablet may contain from 0.5 to about 90 percent of the active compound; however, an artisan would know when amounts outside of this range are necessary. Suitable carriers for powders and tablets are magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, a low melting wax, cocoa butter, and the like. The term “preparation” is intended to include the formulation of the active compound with encapsulating material as carrier providing a capsule in which the active component, with or without carriers, is surrounded by a carrier, which is thus in association with it. Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets, and lozenges can be used as solid forms suitable for oral administration.

For preparing suppositories, a low melting wax, such as an admixture of fatty acid glycerides or cocoa butter, is first melted and the active component is dispersed homogeneously therein, as by stirring. The molten homogenous mixture is then poured into convenient sized molds, allowed to cool, and thereby to solidify.

Formulations suitable for vaginal administration may be presented as pessaries, tampons, creams, gels, pastes, foams or sprays containing in addition to the active ingredient such carriers as are known in the art to be appropriate.

Liquid form preparations include solutions, suspensions, and emulsions, for example, water or water-propylene glycol solutions. For example, parenteral injection liquid preparations can be formulated as solutions in aqueous polyethylene glycol solution. Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution, and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables.

The compounds according to the present invention may thus be formulated for parenteral administration (e.g. by injection, for example bolus injection or continuous infusion) and may be presented in unit dose form in ampoules, pre-filled syringes, small volume infusion or in multi-dose containers with an added preservative. The pharmaceutical compositions may take such forms as suspensions, solutions, or emulsions in oily or aqueous vehicles, and may contain formulatory agents such as suspending, stabilizing and/or dispersing agents. Alternatively, the active ingredient may be in powder form, obtained by aseptic isolation of sterile solid or by lyophilization from solution, for constitution with a suitable vehicle, e.g. sterile, pyrogen-free water, before use.

Aqueous formulations suitable for oral use can be prepared by dissolving or suspending the active component in water and adding suitable colorants, flavours, stabilizing and thickening agents, as desired.

Aqueous suspensions suitable for oral use can be made by dispersing the finely divided active component in water with viscous material, such as natural or synthetic gums, resins, methylcellulose, sodium carboxymethylcellulose, or other well known suspending agents.

Also included are solid form preparations which are intended to be converted, shortly before use, to liquid form preparations for oral administration. Such liquid forms include solutions, suspensions, and emulsions. These preparations may contain, in addition to the active component, colorants, flavors, stabilizers, buffers, artificial and natural sweeteners, dispersants, thickeners, solubilizing agents, and the like.

For topical administration to the epidermis the compounds according to the invention may be formulated as ointments, creams or lotions, or as a transdermal patch.

Ointments and creams may, for example, be formulated with an aqueous or oily base with the addition of suitable thickening and/or gelling agents. Lotions may be formulated with an aqueous or oily base and will in general also contain one or more emulsifying agents, stabilizing agents, dispersing agents, suspending agents, thickening agents, or coloring agents.

Formulations suitable for topical administration in the mouth include lozenges comprising active agent in a flavored base, usually sucrose and acacia or tragacanth; pastilles comprising the active ingredient in an inert base such as gelatin and glycerin or sucrose and acacia; and mouthwashes comprising the active ingredient in a suitable liquid carrier.

Solutions or suspensions are applied directly to the nasal cavity by conventional means, for example with a dropper, pipette or spray. The formulations may be provided in single or multi-dose form. In the latter case of a dropper or pipette, this may be achieved by the patient administering an appropriate, predetermined volume of the solution or suspension. In the case of a spray, this may be achieved for example by means of a metering atomizing spray pump.

Administration to the respiratory tract may also be achieved by means of an aerosol formulation in which the active ingredient is provided in a pressurized pack with a suitable propellant. If the compounds of the present invention or pharmaceutical compositions comprising them are administered as aerosols, for example as nasal aerosols or by inhalation, this can be carried out, for example, using a spray, a nebulizer, a pump nebulizer, an inhalation apparatus, a metered inhaler or a dry powder inhaler. Pharmaceutical forms for administration of the compounds of the present invention as an aerosol can be prepared by processes well-known to the person skilled in the art. For their preparation, for example, solutions or dispersions of the compounds of the present invention in water, water/alcohol mixtures or suitable saline solutions can be employed using customary additives, for example benzyl alcohol or other suitable preservatives, absorption enhancers for increasing the bioavailability, solubilizers, dispersants and others, and, if appropriate, customary propellants, for example include carbon dioxide, CFC's, such as, dichlorodifluoromethane, trichlorofluoromethane, or dichlorotetrafluoroethane; and the like. The aerosol may conveniently also contain a surfactant such as lecithin. The dose of drug may be controlled by provision of a metered valve.

In formulations intended for administration to the respiratory tract, including intranasal formulations, the compound will generally have a small particle size for example of the order of 10 microns or less. Such a particle size may be obtained by means known in the art, for example by micronization. When desired, formulations adapted to give sustained release of the active ingredient may be employed.

Alternatively the active ingredients may be provided in the form of a dry powder, for example, a powder mix of the compound in a suitable powder base such as lactose, starch, starch derivatives such as hydroxypropylmethyl cellulose and polyvinylpyrrolidone (PVP). Conveniently the powder carrier will form a gel in the nasal cavity. The powder composition may be presented in unit dose form for example in capsules or cartridges of, e.g., gelatin, or blister packs from which the powder may be administered by means of an inhaler.

The pharmaceutical preparations are preferably in unit dosage forms. In such form, the preparation is subdivided into unit doses containing appropriate quantities of the active component. The unit dosage form can be a packaged preparation, the package containing discrete quantities of preparation, such as packeted tablets, capsules, and powders in vials or ampoules. Also, the unit dosage form can be a capsule, tablet, cachet, or lozenge itself, or it can be the appropriate number of any of these in packaged form.

Tablets or capsules for oral administration and liquids for intravenous administration are preferred compositions.

The compounds according to the invention may optionally exist as pharmaceutically acceptable salts including pharmaceutically acceptable acid addition salts prepared from pharmaceutically acceptable non-toxic acids including inorganic and organic acids. Representative acids include, but are not limited to, acetic, benzenesulfonic, benzoic, camphorsulfonic, citric, ethenesulfonic, dichloroacetic, formic, fumaric, gluconic, glutamic, hippuric, hydrobromic, hydrochloric, isethionic, lactic, maleic, malic, mandelic, methanesulfonic, mucic, nitric, oxalic, pamoic, pantothenic, phosphoric, succinic, sulfuric, tartaric, oxalic, p-toluenesulfonic and the like, such as those pharmaceutically acceptable salts listed in Journal of Pharmaceutical Science, 66, 2 (1977); incorporated herein by reference in its entirety.

The acid addition salts may be obtained as the direct products of compound synthesis. In the alternative, the free base may be dissolved in a suitable solvent containing the appropriate acid, and the salt isolated by evaporating the solvent or otherwise separating the salt and solvent. The compounds of this invention may form solvates with standard low molecular weight solvents using methods known to the skilled artisan.

Some embodiments of the present invention include a method of producing a pharmaceutical composition for “combination-therapy” comprising admixing at least one compound according to any of the compound embodiments disclosed herein, together with at least one known pharmaceutical agent as described herein and a pharmaceutically acceptable carrier.

It is noted that when the 5-HT_(2A) receptor modulators are utilized as active ingredients in a pharmaceutical composition, these are not intended for use only in humans, but in other non-human mammals as well. Indeed, recent advances in the area of animal health-care mandate that consideration be given for the use of active agents, such as 5-HT_(2A) receptor modulators, for the treatment of a 5-HT_(2A) mediated disease or disorder in domestic animals (e.g., cats and dogs) and in other domestic animals (e.g., such as cows, chickens, fish, etc.). Those of ordinary skill in the art are readily credited with understanding the utility of such compounds in such settings.

Other Utilities

Another object of the present invention relates to radio-labeled compounds of the present invention that would be useful not only in radio-imaging but also in assays, both in vitro and in vivo, for localizing and quantitating the 5-HT_(2A) receptor in tissue samples, including human, and for identifying 5-HT_(2A) receptor ligands by inhibition binding of a radio-labeled compound. It is a further object of this invention to develop novel 5-HT_(2A) receptor assays of which comprise such radio-labeled compounds.

The present invention embraces isotopically-labeled compounds of the present invention. An “isotopically” or “radio-labeled” compounds are those which are identical to compounds disclosed herein, but for the fact that one or more atoms are replaced or substituted by an atom having an atomic mass or mass number different from the atomic mass or mass number typically found in nature (i.e., naturally occurring). Suitable radionuclides that may be incorporated in compounds of the present invention include, but are not limited to, ²H (also written as D for deuterium), ³H (also written as T for tritium), ¹¹C, ¹³C, ¹⁴C, ¹³N, ¹⁵N, ¹⁵O, ¹⁷O, ¹⁸O, ¹⁸F, ³⁵S, ³⁶Cl, ⁸²Br, ⁷⁵Br, ⁷⁶Br, ⁷⁷Br, ¹²³I, ¹²⁴I, ¹²⁵I, and ¹³¹I. The radionuclide that is incorporated in the instant radio-labeled compounds will depend on the specific application of that radio-labeled compound. For example, for in vitro 5-HT_(2A) receptor labeling and competition assays, compounds that incorporate ³H, ¹⁴C, ⁸²Br, ¹²⁵I, ¹³¹I, ³⁵S or will generally be most useful. For radio-imaging applications ¹¹C, ¹⁸F, ¹²⁵I, ¹²³I, ¹²⁴I, ¹³¹I, ⁷⁵Br, ⁷⁶Br or ⁷⁷Br will generally be most useful.

It is understood that a “radio-labeled” or “labeled compound” is a compound of Formula (Ia) that has incorporated at least one radionuclide; in some embodiments the radionuclide is selected from the group consisting of ³H, ¹⁴C, ¹²⁵I, ³⁵S and ⁸²Br. Certain isotopically-labeled compounds of the present invention are useful in compound and/or substrate tissue distribution assays. In some embodiments the radionuclide ³H and/or ¹⁴C isotopes are useful in these studies. Further, substitution with heavier isotopes such as deuterium (i.e., ²H) may afford certain therapeutic advantages resulting from greater metabolic stability (e.g., increased in vivo half-life or reduced dosage requirements) and hence may be preferred in some circumstances. Isotopically labeled compounds of the present invention can generally be prepared by following procedures analogous to those disclosed in the Schemes supra and Examples infra, by substituting an isotopically labeled reagent for a non-isotopically labeled reagent. Other synthetic methods that are useful are discussed infra. Moreover, it should be understood that all of the atoms represented in the compounds of the invention can be either the most commonly occurring isotope of such atoms or the more scarce radio-isotope or nonradio-active isotope.

Synthetic methods for incorporating radio-isotopes into organic compounds are applicable to compounds of the invention and are well known in the art. These synthetic methods, for example, incorporating activity levels of tritium into target molecules, are as follows:

A. Catalytic Reduction with Tritium Gas—This procedure normally yields high specific activity products and requires halogenated or unsaturated precursors.

B. Reduction with Sodium Borohydride [³H]—This procedure is rather inexpensive and requires precursors containing reducible functional groups such as aldehydes, ketones, lactones, esters, and the like.

C. Reduction with Lithium Aluminum Hydride [³H]—This procedure offers products at almost theoretical specific activities. It also requires precursors containing reducible functional groups such as aldehydes, ketones, lactones, esters, and the like.

D. Tritium Gas Exposure Labeling—This procedure involves exposing precursors containing exchangeable protons to tritium gas in the presence of a suitable catalyst.

E. N-Methylation using Methyl Iodide [³H]—This procedure is usually employed to prepare O-methyl or N-methyl (³H) products by treating appropriate precursors with high specific activity methyl iodide (³H). This method in general allows for higher specific activity, such as for example, about 70-90 Ci/mmol.

Synthetic methods for incorporating activity levels of ¹²⁵I into target molecules include:

A. Sandmeyer and like reactions—This procedure transforms an aryl or heteroaryl amine into a diazonium salt, such as a tetrafluoroborate salt, and subsequently to ¹²⁵I labeled compound using Na ¹²⁵I. A represented procedure was reported by Zhu, D.-G. and co-workers in J. Org. Chem. 2002, 67, 943-948.

B. Ortho ¹²⁵Iodination of phenols—This procedure allows for the incorporation of ¹²⁵I at the ortho position of a phenol as reported by Collier, T. L. and co-workers in J. Labeled Compd Radiopharm. 1999, 42, S264-S266.

C. Aryl and heteroaryl bromide exchange with ¹²⁵I—This method is generally a two step process. The first step is the conversion of the aryl or heteroaryl bromide to the corresponding tri-alkyltin intermediate using for example, a Pd catalyzed reaction [i.e. Pd(Ph₃P)4] or through an aryl or heteroaryl lithium, in the presence of a tri-alkyltinhalide or hexaalkylditin [e.g., (CH₃)₃SnSn(CH₃)₃]. A represented procedure was reported by Bas, M.-D. and co-workers in J. Labeled Compd Radiopharm. 2001, 44, S280-S282.

A radio-labeled 5-HT_(2A) receptor compound of Formula (Ia) can be used in a screening assay to identify/evaluate compounds. In general terms, a newly synthesized or identified compound (i.e., test compound) can be evaluated for its ability to reduce binding of the “radio-labeled compound of Formula (Ia)” to the 5-HT_(2A) receptor. Accordingly, the ability of a test compound to compete with the “radio-labeled compound of Formula (Ia)” for the binding to the 5-HT_(2A) receptor directly correlates to its binding affinity.

The labeled compounds of the present invention bind to the 5-HT_(2A) receptor. In one embodiment the labeled compound has an IC₅₀ less than about 500 μM, in another embodiment the labeled compound has an IC₅₀ less than about 100 μM, in yet another embodiment the labeled compound has an IC₅₀ less than about 10 μM, in yet another embodiment the labeled compound has an IC₅₀ less than about 1 μM, and in still yet another embodiment the labeled inhibitor has an IC₅₀ less than about 0.1 μM.

The mixture was cooled on an ice bath and DIAD (38.8 μl, 200 μmol) was added. The solution was stirred at 0° C. for a half hour and then (R)-tert-butyl 1-hydroxypropan-2-ylcarbamate (35.0 mg, 200 μmol), pre-dissolved in THF (0.3 mL) was added. The reaction was warmed to r.t. and stirred for 4 hours. The crude LC/MS showed that some product formed (˜60% complete, as judged from the LC/MS). Pushing the reaction by heating or extending the run time did not seem to improve the yield. Thus, the solvent was evaporated, the resulting oil was re-dissolved in CH₂Cl₂ (0.5 mL) and TFA (0.5 mL) was added (in order to remove the Boc-protecting group from the amine). The reaction was stirred overnight at room temperature. The next day, the solvent was evaporated and the oil was dissolved in DMSO (1 mL). The product was purified by Prep LC/MS (0-60% B, 30 min) to yield N-[4-((R)-2-amino-propoxy)-3-(4-chloro-2-methyl-2H-pyrazol-3-yl)-phenyl]-2-fluoro-4-methoxy-benzamide trifluoroacetate (11.0 mg, 1.83 mmol, 15.0%) as a colorless oil.

Triphenylphosphine (299 mg, 1141 μmol) was added and the reaction was stirred for 10 min. The reaction was then allowed to warm to r.t. and stirred for 18 hours. After this time, a TLC suggested that the reaction was complete (silica, 50% EtOAc/Hexanes, Ninhydrin stain). The solvent was removed and the product purified by column chromatography (0, 5, 10, 15, 20% EtOAc/Hexanes) to yield (R)-tert-butyl 1-bromopropan-2-ylcarbamate (67.1 mg, 0.28 mmol, 49.3%) as a colorless oil that turned solid upon standing.

The reaction was heated in a microwave at 100° C. for an hour. After this time, the crude LC/MS showed that the reaction was nearly complete. Thus, the solvent was evaporated and the resulting material was extracted (3 mL each of H₂O and CH₂Cl₂). The aqueous layer was extracted again with CH₂Cl₂ (3 mL). The combined organic layer was dried over MgSO₄, filtered, and concentrated. The product was purified by column chromatography (0, 20, 50, 70, 100% EtOAc/Hexanes) to yield tert-butyl(R)-1-(4-amino-2-(1-methyl-1H-pyrazol-5-yl)phenoxy)propan-2-ylcarbamate (487 mg, 1.41 mmol, 50.7%) as a light brown colored oil.

The reaction mixture was heated briefly with a heat gun (˜50° C.) and then stirred at r.t. for 4 hours. After this time, the crude LC/MS showed that the reaction was fairly complete. Thus, the solvent was evaporated, the resulting oil was re-dissolved in CH₂Cl₂ (0.5 mL) and TEA (0.5 mL) was added (in order to remove the Boc-protecting group from the amine). The reaction was stirred overnight at room temperature. The next day, the solvent was evaporated and the oil was dissolved in DMSO (1 mL). The product was purified by Prep LC/MS (5-60% B, 30 minutes) to afford 2,2-difluoro-benzo[1,3]dioxole-5-carboxylic acid [4-((R)-2-amino-propoxy)-3-(2-methyl-2H-pyrazol-3-yl)-phenyl]-amide trifluoroacetate (11.8 mg, 0.021 mmol, 35.7%) as a white solid that was very hygroscopic.

Di-tert-butyl dicarbonate (1.80 mL, 8.40 mmol) was added and the reaction stirred for 10 min at 0° C. After this time, the reaction was allowed to warm to r.t. and stirring continued for 2 hours. The solvent was evaporated and the reaction was extracted (50 mL each of H₂O/NaHCO₃ and CH₂Cl₂). The aqueous layer was extracted again (2×50 mL CH₂Cl₂). The combined organic layer was dried and concentrated yielding 2-(tert-butoxycarbonyl)-4,4,4-trifluorobutanoic acid (1.94 g, 7.39 mmol, 96.8% yield) as a white solid.

A solution of 2-(tert-butoxycarbonyl)-4,4,4-trifluorobutanoic acid (1.64 g, 6.38 mmol) and DMA (1.33 mL, 7.65 mmol) in anhydrous THF (15 mL) was cooled on an ice bath. Ethyl chloroformate (0.674 mL, 7.01 mmol) was added slowly via syringe. After the addition, the reaction mixture was warmed to r.t. and stirred for 2 hours (a white solid ppt formed in this time). After 2 hours, the precipitate was filtered and washed with anhydrous THF (4 mL). Lithium borohydride (6.38 mL, 12.8 mmol) was slowly added to the filtrate (vigorous bubbling was observed). The solution was stirred for 2 hours and the reaction progress was checked by crude LC/MS. Once the reaction was complete, most of the THF solvent was evaporated and an extraction was performed (100 mL each of H₂O/NaCl and EtOAc). The aqueous layer was extracted again (2×100 mL EtOAc). The combined organic layer was dried over MgSO₄, filtered, and concentrated. The product was purified by column chromatography (0, 20, 50, 60, 70% EtOAc/Hexanes) to yield tert-butyl 4,4,4-trifluoro-1-hydroxybutan-2-ylcarbamate (1.24 g, 5.10 mmol, 80.0%) as a white solid. LCMS 244.0 (M+H); ¹H NMR (400 MHz, MeOH-d₄) δ ppm 1.45 (s, 9 H), 2.21-2.38 (m, 1 H), 2.41-2.57 (m, 1 H), 3.44 (dd, J=11.12, 6.57 Hz, 1 H), 3.55 (dd, J=11.12, 5.05 Hz, 1 H), 3.84-3.97 (m, 1 H).

N-(3-(4-chloro-1-methyl-1H-pyrazol-5-yl)-4-hydroxyphenyl)-2-fluoro-4-methoxybenzamide (20.0 mg, 53.2 μmol) was dissolved in anhydrous THF (0.3 mL). Triphenylphosphine (15.4 mg, 58.5 μmol), pre-dissolved in anhydrous THF (0.1 mL) was added to the N-(3-(4-chloro-1-methyl-1H-pyrazol-5-yl)-4-hydroxyphenyl)-2-fluoro-4-methoxybenzamide/THF solution. The reaction was stirred for 5 minutes and then DIAD (16.6 μl, 85.2 μmol), pre-dissolved in anhydrous THF (0.1 mL) was added to the reaction. The mixture was stirred at r.t. for 5 more minutes and then tert-butyl 4,4,4-trifluoro-1-hydroxybutan-2-ylcarbamate (16.2 mg, 66.5 mmol), pre-dissolved in anhydrous THF (0.1 mL) was added. The reaction was then stirred for 4 hours and checked by LC/MS. While the reaction had not gone to completion, pushing the reaction by heating or extending the reaction time did not seem to improve the yield. Thus, the solvent was evaporated, the resulting oil re-suspended in CH₂Cl₂ (0.5 mL) and TFA (20.5 μl, 266 μmol) was added (to remove the Boc-protecting group from the amine). The reaction was stirred overnight at room temperature. The next day, the solvent was removed and the resulting oil was re-dissolved in DMSO (1 mL). The product was purified by Prep LC/MS (0-50% B, 30 min) to yield N-[4-(2-amino-4,4,4-trifluoro-butoxy)-3-(4-chloro-2-methyl-2H-pyrazol-3-yl)-phenyl]-2-fluoro-4-methoxy-benzamide trifluoroacetate (8.1 mg, 13.0 μmol, 24.5%) as a colorless oil.

Example 9 Receptor Expression

A. pCMV

Although a variety of expression vectors are available to those in the art, it is preferred that the vector utilized be pCMV. This vector was deposited with the American Type Culture Collection (ATCC) on Oct. 13, 1998 (10801 University Blvd., Manassas, Va. 20110-2209 USA) under the provisions of the Budapest Treaty for the International Recognition of the Deposit of Microorganisms for the Purpose of Patent Procedure. The DNA was tested by the ATCC and determined to be viable. The ATCC has assigned the following deposit number to pCMV: ATCC #203351.

B. Transfection Procedure

For the IP accumulation assay (Example 10), HEK293 cells were transfected while for the DOI binding assay (Example 11) COS7 cells were transfected. Several protocols well known in the art can be used to transfect cells. The following protocol is representative of the transfection procedures used herein for COS7 or 293 cells.

On day one, COS-7 cells were plated onto 24 well plates, usually 1×10⁵ cells/well or 2×10⁵ cells/well, respectively. On day two, the cells were transfected by first mixing 0.25 μg cDNA in 50 μL serum-free DMEM/well and then 2 μl lipofectamine in 50 μL serum-free DMEM/well. The solutions (“transfection media”) were gently mixed and incubated for 15-30 minutes at room temperature. The cells were washed with 0.5 mL PBS and then 400 μL of serum free media was mixed with the transfection media and added to the cells. The cells were then incubated for 3-4 hours at 37° C./5% CO₂. Then the transfection media was removed and replaced with 1 mL/well of regular growth media.

For 293 cells, on day one, 13×10⁶ 293 cells per 150 mm plate were plated out. On day two, 2 mL of serum OptimemI (Invitrogen Corporation) was added per plate followed by addition of 60 μL of lipofectamine and 16 μg of cDNA. Note that lipofectamine must be added to the OptimemI and mixed well before addition of cDNA. While complexes between lipofectamine and the cDNA are forming, media was carefully aspirated and cells were gently rinsed with 5 mL of OptimemI media followed by careful aspiration. Then 12 mL of OptimemI was added to each plate and 2 mL of transfection solution was added followed by a 5 hour incubation at 37° C. in a 5% CO₂ incubator. Plates were then carefully aspirated and 25 mL of Complete Media were added to each plate and cells were then incubated until used.

Example 10 Inositol Phosphate (IP) Accumulation Assays

Compounds of the invention are tested for their ability to activate a 5-HT_(2A) receptor clone using an IP accumulation assay. Briefly, HEK293 cells are transiently transfected with a pCMV expression vector containing a human 5-HT_(2A) receptor (for the sequence of the receptor see U.S. Pat. No. 6,541,209, SEQ ID NO:24) as described in Example 9. An IP accumulation assay is performed as described below.

B. Constitutively Active 5-HT_(2A) Receptor

Compounds of the invention are tested for their ability to inhibit a constitutively active 5-HT_(2A) receptor clone using an IP accumulation assay. Briefly, 293 cells are transiently transfected with a pCMV expression vector containing a constitutively active human 5-HT_(2A) receptor (for the sequence of the receptor see U.S. Pat. No. 6,541,209, SEQ ID NO:30) as described in Example 9. The constitutively active human 5-HT_(2A) receptor contained the human 5-HT_(2A) receptor described in part A except that intracellular loop 3 (IC3) and the cytoplamic tail are replaced by the corresponding human INI 5-HT2C cDNA. An JP accumulation assay is performed as described below.

C. IP Accumulation Assay Protocol

On the day after transfections, media is removed and the cells are washed with 5 mL PBS followed by careful aspiration. Cells are then trypsinized with 2 mL of 0.05% trypsin for 20-30 seconds followed by addition of 10 mL of warmed media, gently titurated to dissociate cells, and an additional 13 mL of warmed media is gently added. Cells are then counted and 55,000 cells are added to 96-well sterile poly-D-lysine treated plates. Cells are allowed to attach over a six hour incubation at 37° C. in a 5% CO₂ incubator. Media is then carefully aspirated and 100 μL of warm inositol-free media plus 0.5 μCi ³H-inositol is added to each well and the plates are incubated for 18-20 hours at 37° C. in a 5% CO₂ incubator.

On the next day, media is carefully aspirated and then 0.1 mL of assay medium is added containing inositol-free/serum free media, 10 μM pargyline, 10 mM lithium chloride, and test compound at indicated concentrations. The plates are then incubated for three hours at 37° C. and then wells are carefully aspirated. Then 200 μL of ice-cold 0.1M formic acid is added to each well. Plates can then be frozen at this point at −80° C. until further processed. Frozen plates are then thawed over the course of one hour, and the contents of the wells (approximately 220 μL) are placed over 400 μL of washed ion-exchange resin (AG 1-X8) contained in a Multi Screen Filtration plate and incubated for 10 minutes followed by filtration under vacuum pressure. Resin is then washed nine times with 200 μL of water and then tritiated inositol phosphates (IP, IP2, and IP3) are eluted into a collecting plate by the addition of 200 μl of 1M ammonium formate and an additional 10 minute incubation. The elutant is then transferred to 20 mL scintillation vials, 8 mL of SuperMix or Hi-Safe scintillation cocktails is added, and vials are counted for 0.5-1 minutes in a Wallac 1414 scintillation counter.

Example 11 Binding Assays

Compounds of the invention were tested for their ability to bind to a 5-HT_(2A) receptor clone membrane preparation using a radioligand binding assay. Briefly, COS cells were transiently transfected with a pCMV expression vector containing a human 5-HT_(2A) receptor (for the sequence of the receptor see U.S. Pat. No. 6,541,209, SEQ ID NO:24) as described in Example 9.

A. Preparation of Crude Membrane Preparations for Radioligand Binding Assays

COS7 cells transfected with recombinant human 5-HT_(2A) receptors were cultured for 48 hr post transfection, collected, washed with ice-cold phosphate buffered saline, pH7.4 (PBS), and then centrifuged at 48,000×g for 20 min at 4° C. The cell pellet was then resuspended in wash buffer containing 20 mM HEPES pH 7.4 and 0.1 mM EDTA, homogenized on ice using a Brinkman polytron, and recentrifuged at 48,000×g for 20 min. at 4° C. The resultant pellet was then resuspended in 20 mM HEPES, pH 7.4, homogenized on ice, and centrifuged (48,000×g for 20 min at 4° C.). Crude membrane pellets were stored at −80° C. until used for radioligand binding assays.

B. [¹²⁵I]DOI Radioligand Binding Assay

Radioligand binding assays for human 5-HT_(2A) receptor was conducted using the 5-HT₂ agonist [¹²⁵]DOI as radioligand. To define nonspecific binding, 10 μM DOI was used for all assays. For competitive binding studies, 0.5 nM [¹²⁵]DOI was used and compounds were assayed over a range of 0.01 nM to 10 μM. Assays were conducted in a total volume of 200 μl in 96-well Perkin Elmer GF/C filter plates in assay buffer (50 mM Tris-HCl, pH 7.4, 0.5 mM EDTA, 5 mM MgCl₂, and 10 μM pargyline). Assay incubations were performed for 60 min at room temperature and were terminated by rapid filtration under vacuum pressure of the reaction mixture over Whatman GF/C glass fiber filters presoaked in 0.5% PEI using a Brandell cell harvestor. Filters were then washing several times with ice-cold wash buffer (50 mM Tris-HCl, pH 7.4). Plates were then dried at room temperature and counted in a Wallac microBeta scintillation counter. Certain compounds of the present invention and their corresponding activity values are shown in the following table.

Example 12 In Vitro Human Platelet Aggregation Assays

Compounds of the invention were tested for their ability to aggregate human platelets. Aggregation assays were performed using a Chrono-Log Optical aggregometer model 410. Human blood (˜100 mL) was collected from human donors into glass Vacutainers containing 3.8% sodium citrate (light blue tops) at room temperature. Platelet rich plasma (PRP) was isolated via centrifugation at 100 g for 15 min at room temperature. After removal of the aqueous PRP layer, the platelet poor plasma (PPP) was prepared via high speed centrifugation at 2400 g for 20 min. Platelets were counted and their concentration was set to 250,000 cells/μl by dilution with PPP. Aggregation assays were conducted according to the manufacturer's specifications. Briefly, a suspension of 450 μl PRP was stirred in a glass cuvette (1200 rpm) and, after baseline was established, 1 μM ADP followed by either saline or 1 μM 5HT and compound of interest (at desired concentrations) were added and the aggregation response recorded. The concentration of ADP used causes approximately 10-20% of maximal aggregation. The 5-HT concentration corresponded to the concentration which produced maximal potentiation. Percent inhibition of aggregation was calculated from the maximum decrease in optical density of the controls and of the samples containing inhibitors. Only the synergistic effect was assessed. Certain compounds of the invention had activity values ranging from about 10 μM to about 2.0 nM in this assay.

Example 13 Efficacy of Compounds of the Invention in the Attenuation of DOI-Induced Hypolocomotion in Rats

In this example, compounds of the invention can be tested for inverse agonist activity by determining whether these compounds could attenuate DOI-induced hypolocomotion in rats in a novel environment. DOI is a potent 5-HT_(2A/2C) receptor agonist that crosses the blood-brain barrier. The standard protocol used is described briefly below.

Animals:

Male Sprague-Dawley rats weighing between 200-300 g are used for all tests. Rats are housed three to four per cage. These rats are naïve to experimental testing and drug treatment. Rats are handled one to three days before testing to acclimate them to experimental manipulation. Rats are fasted overnight prior to testing.

Compounds:

(R)-DOI HCl (C₁₁H₁₆INO₂HCl) can be obtained from Sigma-Aldrich, and is dissolved in 0.9% saline. Compounds of the invention are dissolved in 100% PEG400. DOI is injected s.c. in a volume of 1 mL/kg, while compounds of the invention are administered p.o. in a volume of 21 mL/kg.

Procedure:

The “Motor Monitor” (Hamilton-Kinder, Poway, Calif.) is used for all activity measurement. This apparatus recorded rears using infrared photobeams.

Locomotor activity testing is conducted during the light cycle (0630-1830) between 9:00 a.m. and 4:00 p.m. Animals are allowed 30 min acclimation to the testing room before testing began.

In determining the effects of compounds of the invention on DOI-induced hypoactivity, animals are first injected with vehicle or the compound of the invention (50 μmol/kg) in their home cages. Sixty minutes later, saline or DOI (0.3 mg/kg salt) is injected. 10 min after DOI administration, animals are placed into the activity apparatus and rearing activity is measured for 10 minutes.

Statistics and Results:

Results (total rears over 10 minutes) are analyzed by t-test. P<0.05 is considered significant.

Example 14 In Vitro Binding of 5-HT_(2A) Receptor

Animals:

Animals (Sprague-Dawley rats) are sacrificed and brains are rapidly dissected and frozen in isopentane maintained at −42° C. Horizontal sections are prepared on a cryostat and maintained at −20° C.

LSD Displacement Protocol:

Lysergic acid diethylamide (LSD) is a potent 5-HT_(2A) receptor and dopamine D₂ receptor ligand. An indication of the selectivity of compounds for either or both of these receptors involves displacement of radiolabeled-bound LSD from pre-treated brain sections. For these studies, radiolabeled ¹²⁵I-LSD (NEN Life Sciences, Boston, Mass., Catalogue number NEX-199) can be utilized; spiperone (RBI, Natick, Mass. Catalogue number s-128) a 5-HT_(2A) receptor and dopamine D₂ receptor antagonist, can also utilized. Buffer consists of 50 nanomolar TRIS-HCl, pH 7.4.

Brain sections are incubated in (a) Buffer plus 1 nanomolar ¹²⁵I-LSD; (b) Buffer plus 1 nanomolar ¹²⁵I-LSD and 1 micromolar spiperone; or Buffer plus 1 nanomolar ¹²⁵I-LSD and 1 micromolar Compound of interest for 30 minutes at room temperature. Sections are then washed 2×10 minutes at 4° C. in Buffer, followed by 20 seconds in distilled H₂O, Slides are then air-dried.

After drying, sections are apposed to x-ray film (Kodak Hyperfilm) and exposed for 4 days.

Example 15 Serotonin 5-HT_(2A) Receptor Occupancy Studies in Monkey

In this example, the 5-HT_(2A) receptor occupancy of a compound of the invention can be measured. The study can be carried out in rhesus monkeys using PET and ¹⁸F-altanserin.

Radioligand:

The PET radioligand used for the occupancy studies is ¹⁸F-altanserin. Radiosynthesis of ¹⁸F-altanserin is achieved in high specific activities and is suitable for radiolabeling 5-HT_(2A) receptors in vivo (see Staley et al., Nucl. Med. Biol., 28:271-279 (2001) and references cited within). Quality control issues (chemical and radiochemical purity, specific activity, stability etc) and appropriate binding of the radioligand are verified in rat brain slices prior to use in PET experiments.

Drug Doses and Formulations:

Briefly, the radiopharmaceutical is dissolved in sterile 0.9% saline, pH approx 6-7. The compounds of the invention are dissolved in 60% PEG 400-40% sterile saline on the same day of the PET experiment.

Serotonin 5-HT_(2A) occupancy studies in humans have been reported for M100,907 (Grunder et al., Neuropsychopharmacology, 17:175-185 (1997), and Talvik-Lofti et al., Psychopharmacology, 148:400-403 (2000)). High occupancies of the 5-HT_(2A) receptors have been reported for various oral doses (doses studied ranged from 6 to 20 mg). For example, an occupancy of >90% was reported for a dose of 20 mg (Talvik-Lofti et al., supra), which translates to approx. 0.28 mg/kg. It may therefore be anticipated that an i.v. dose of 0.1 to 0.2 mg/kg of M100,907 is likely to provide high receptor occupancy. A 0.5 mg/kg dose of a Compound of the invention can be used in these studies.

PET Experiments:

The monkey is anesthetized by using ketamine (10 mg/kg) and is maintained using 0.7 to 1.25% isoflurane. Typically, the monkey has two i.v. lines, one on each arm. One i.v. line is used to administer the radioligand, while the other line is used to draw blood samples for pharmacokinetic data of the radioligand as well as the cold drugs. Generally, rapid blood samples are taken as the radioligand is administered which then taper out by the end of the scan. A volume of approximately 1 mL of blood is taken per time point, which is spun down, and a portion of the plasma is counted for radioactivity in the blood.

An initial control study is carried out in order to measure baseline receptor densities. PET scans on the monkey are separated by at least two weeks. Unlabeled Compound of the invention is administered intravenously, dissolved in 80% PEG 400:40% sterile saline.

PET Data Analysis:

PET data are analyzed by using cerebellum as the reference region and using the distribution volume region (DVR) method. This method has been applied for the analysis of ¹⁸F-altanserin PET data in nonhuman primate and human studies (Smith et al., Synapse, 30:380-392 (1998).

Example 16 The Effect of Compounds of the Invention and Zolpidem on Delta Power in Rats

In this example, the effect of Compounds of the invention on sleep and wakefulness can be compared to the reference drug zolpidem. Drugs are administered during the middle of the light period (inactivity period).

Briefly, Compounds of the invention are tested for their effects on sleep parameters and are compared to zolpidem (5.0 mg/kg, Sigma, St. Louis, Mo.) and vehicle control (80% Tween 80, Sigma, St. Louis, Mo.). A repeated measures design is employed in which each rat is to receive seven separate dosings via oral gavage. The first and seventh dosings are vehicle and the second through sixth are the test compounds and zolpidem given in counter-balanced order. Since all dosings are administered while the rats are connected to the recording apparatus, 60% CO₂/40% O₂ gas is employed for light sedation during the oral gavage process. Rats are fully recovered within 60 seconds following the procedure. A minimum of three days elapses between dosings. In order to test the effect of the compounds on sleep consolidation, dosing occurs during the middle of the rats' normal inactive period (6 hours following lights on). Dosing typically occurs between 13:15 and 13:45 using a 24 hour notation. All dosing solutions are made fresh on the day of dosing. Following each dosing, animals are continuously recorded until lights out the following day (˜30 hours).

Animal Recording and Surgical Procedures:

Animals are housed in a temperature controlled recording room under a 12/12 light/dark cycle (lights on at 7:00 am) and have food and water available ad libitum. Room temperature (24±2° C.), humidity (50±120% relative humidity) and lighting conditions are monitored continuously via computer. Drugs are administered via oral gavage as described above, with a minimum of three days between dosings. Animals are inspected daily in accordance with NIH guidelines.

Eight male Wistar rats (300+25 g; Charles River, Wilmington, Mass.) are prepared with chronic recording implants for continuous electroencephalograph (EEG) and electromyograph (EMG) recordings. Under isoflurane anesthesia (1-4%), the fur is shaved from the top of the skull and the skin was disinfected with Betadine and alcohol. A dorsal midline incision is made, the temporalis muscle retracted, and the skull cauterized and thoroughly cleaned with a 2% hydrogen peroxide solution. Stainless steel screws (#000) are implanted into the skull and served as epidural electrodes. EEG electrodes are positioned bilaterally at +2.0 mm AP from bregma and 2.0 mm ML and at −6.0 mm AP and 3.0 mm ML. Multi-stranded twisted stainless steel wire electrodes are sutured bilaterally in the neck muscles for recording of the EMG. EMG and EEG electrodes are soldered to a head plug connector that was affixed to the skull with dental acrylic. Incisions are closed with suture (silk 4-0) and antibiotics administered topically. Pain is relieved by a long-lasting analgesic (Buprenorphine) administered intramuscularly once post-operatively. Post-surgery, each animal is placed in a clean cage and observed until it is recovered. Animals are permitted a minimum of one week post-operative recovery before study.

For sleep recordings, animals are connected via a cable and a counter-balanced commutator to a Neurodata model 15 data collection system (Grass-Telefactor, West Warwick, R.I.). The animals are allowed an acclimation period of at least 48 hours before the start of the experiment and are connected to the recording apparatus continuously throughout the experimental period except to replace damaged cables. The amplified EEG and EMG signals are digitized and stored on a computer using SleepSign software (Kissei Comtec, Irvine Calif.).

Data Analysis:

EEG and EMG data are scored visually in 10 second epochs for waking (W), REMS, NREMS. Scored data are analyzed and expressed as time spent in each state per half hour. Sleep bout length and number of bouts for each state are calculated in hourly bins. A “bout” consists of a minimum of two consecutive epochs of a given state. EEG delta power (0.5-3.5 Hz) within NREMS is also analyzed in hourly bins. The EEG spectra during NREMS are obtained offline with a fast Fourier transform algorithm on all epochs without artifact. The delta power is normalized to the average delta power in NREMS between 23:00 and 1:00, a time when delta power is normally lowest.

Data are analyzed using repeated measures ANOVA. Light phase and dark phase data are analyzed separately. Both the treatment effect within each rat and the time by treatment effect within each rat is analyzed. Since two comparisons are made, a minimum value of P<0.025 is required for post hoc analysis. When statistical significance is found from the ANOVAs, t-tests are performed comparing all compounds to vehicle and the test compounds to zolpidem.

Example 17 Efficacy of Compounds of the Invention in the Inhibition of JC Virus Infection of Human Glial Cells

A compound of the invention can be shown to inhibit JC virus infection of human glial cells using the in vitro model of Elphick et al. [Science (2004) 306:1380-1383], essentially as described briefly here.

Cells and JC Virus

The human glial cell line SVG (or a suitable subclone thereof, such as SVG-A) is used for these experiments. SVG is a human glial cell line established by transformation of human fetal glial cells by an origin defective SV40 mutant [Major et al., Proc. Natl. Acad. Sci. USA (1985) 82:1257-1261]. SVG cells are cultured in Eagle's minimum essential medium (Mediatech Inc., Herndon, Va.) supplemented with 10% heat-inactivated fetal bovine serum, and kept in a humidified 37° C. 5% CO₂ incubator.

The Mad-1/SVEΔ strain of JC virus [Vacante et al., Virology (1989) 170:353-361] is used for these experiments. While the host range of JC virus is typically limited to growth in human fetal glial cells, the host range of Mad-1/SVEΔ extends to human kidney and monkey cell types. Mad-1/SVEΔ is propagated in HEK cells. Virus titer is measured by hemagglutination of human type O erythrocytes.

Assay for Inhibition of JC Virus Infection

SVG cells growing on coverslips are pre-incubated at 37° C. for 45 min with or without the compound of the invention diluted in media containing 2% FCS. By way of illustration and not limitation, the compound of the invention is used at a concentration of about 1 nM to about 100 μM, at a concentration of about 10 nM to about 100 μM, at a concentration of about 1 nM to about 10 μM, or at a concentration of about 10 nM to about 10 μM.

JC virus (Mad-1/SVEA) is then added at an MOI of 1.0 and the cells are incubated for 1 hr at 37° C. in the continued presence of the compound of the invention. The cells are then washed 3× in PBS and fed with growth media containing the compound of the invention. At 72 hr post-infection, V antigen positive cells are scored by indirect immunofluorescence (see below). Controls include the addition of the compound of the invention at 24 and 48 h post-infection. The percentage of infected cells in untreated cultures is set at 100%.

Indirect Immunofluorescence

For indirect immunofluorescence analysis of V antigen expression, SVG cells growing on coverslips are fixed in ice cold acetone. To detect V antigen expression, the cells are then incubated for 30 min at 37° C. with a 1:10 dilution of hybridoma supernatant from PAB597. The PA3597 hybridoma produces a monoclonal antibody against the SV40 capsid protein VP1 which has been shown to cross-react with JC virus VP1. The cells are then washed and incubated with goat anti-mouse Alexa Fluor 488 secondary antibody for an additional 30 min. After a final wash, the cells are counterstained with 0.05% Evan's blue, mounted onto glass slides using 90% glycerol in PBS and visualized on Nikon E800 epifluorescent scope. Images are captured using a Hamamatsu digital camera and analyzed using Improvision software.

Example 18 In Vitro Dog Platelet Aggregation Assays

Approximately 50 mL of blood is pooled from 3 male beagles. The protocol for analyzing the effects of compounds on platelet aggregation are identical to those used for human platelets (see Example 12, supra) except 5 μM ADP and 2 μM 5-HT were used to stimulate amplification of platelet aggregation.

Example 19 Ex-Vivo Dog Whole Blood Aggregation

One hour following PO dosing with a test compound whole blood was collected from male beagle dogs in a 5 mL vacutainer with exogenous heparin (5 U/mL) added to vacutainer. Aggregation studies were evaluated by using whole blood Aggregometer (Chronolog Corp.). Briefly, whole blood (400 uL) was added to saline (600 uL) with constant stirring and activated with 5 ug of Collagen (Chronolog Corp.). The serotonin response was obtained by adding 5-HT (Sigma) to final concentration of 2.5 μM. Results: Selected compounds were tested for anti-platelet aggregation activity after single bolus oral dosing. The dose that afforded maximal inhibition of 5-HT amplified platelet aggregation was identified and used for comparison.

Example 20 Rat In Vivo Thrombosis, Bleeding, Aggregation, PK Assay

Thrombosis Formation and Bleeding Time:

This model concomitantly measures thrombus formation, bleeding time, platelet aggregation and drug exposure in a single live dosed rat. Test compounds are administered to male rats (weighing 250-350 g) via PO injection at varying concentrations depending on compound potency ranging from 1 mpk-100 mpk. Animals are then anesthetized using Nembutal approximately 30 min post PO. Once the animal is fully anesthetized using approved surgical techniques the animal's right femoral artery is isolated in 2 different sections approximately 4-6 mm in length, one area for probe placement and one for Ferric Chloride patch positioning. The artery is then allowed to stabilize to allow recovery from the surgery. During stabilization the animal is then intubated and placed on a ventilator (Harvard Apparatus, Inc.) at 75 strokes/min with a volume of 2.5 cubic cm. Following intubation and after stabilization a micro arterial probe (Transonic Systems, Inc) is then placed on the distal isolated femoral artery. Once the probe is in place the flow is monitored using a Powerlab recording system (AD Instruments) to monitor rate of pulsatile flow. A small piece of filter paper soaked in 30% ferric chloride is placed on the area of the artery upstream of the probe for 10 min. After 5 min of Ferric Choloride patch placement the last 3 mm of the rat's tail is removed. The tail is then placed in a saline filled glass vial at 37 degree and the time it took for bleeding to stop is recorded. After the Ferric chloride patch is removed the flow is recorded until the artery is occluded and time to occlusion is recorded.

Whole Blood Aggregation and PK:

Following measurement of bleeding and time to occlusion 5 mL of blood is obtained for ex-vivo aggregation analysis by cardiac puncture in heparin (SU/mL). An additional 500 μL of blood is collected in a separate vacutainer for PK analysis (plasma drug concentration). Ex-vivo aggregation studies are evaluated by using whole blood Aggregometer (Chronolog Corp.). Briefly, whole blood (400 μL) is added to saline (600 μL) with constant stirring and activated with 2.55 μg of Collagen (Chronolog Corp.). The serotonin response is obtained by adding 5-HT (Sigma) to final concentration of 2.5 μM. Results: Test compounds or reference compounds with acceptable levels of binding to rat 5-HT_(2A) receptors are evaluated for effects of thrombus formation, bleeding and platelet activity in a single model. This allows for the most accurate demonstration of separation of the test compound effects on platelet mediated thrombus formation from effects on bleeding.
